Infrared fog penetration
Although thermal imaging cameras can see in total darkness, through light fog, light rain and snow, the distance they can see is affected by these atmospheric conditions.

Description:The various appearances of "one embodiment", "an embodiment" or "some embodiments" do not necessarily all refer to the same embodiments. Sensors Unlimited sensors do not require the complex and costly cryogenic cooling systems found in many infrared imaging systems, greatly increasing reliability and installation flexibility. Often combined with long wave infrared sensors, enhanced vision systems present a "view ahead" to pilots on a head down or heads up HUD cockpit display, namely in Synthetic Vision Information Systems. Current systems use spectral band ranges between 1. In general, the materials for optical elements , , and are selected to achieve a balanced and stable optical set with respect to temperature and wavelength range. Not only did the device Billmers had built with the Navy present an elegant solution to a difficult problem, but it had already been demonstrated to be effective, he says. Barium fluoride, cesium iodide, cadmium telluride, calcium fluoride, lithium fluoride, zinc sulfide, sapphire and a chalcogenide composition; and devoid of silicon, arranged to confer a spectral range starting from a specified wavelength that is shorter than a transmittance threshold of silicon and comprising a short-wavelength infrared SWIR range and at least one of:
